1'0 a/L whom itmaty concern:

Be it known that I, Parlor 'RAYMoNn Ganrsr, -a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented or discovered certain new andusefuli' Improvements in Plating-Separating Devices, 5f whic'hthe following is a specifica:

tion, reference being had'therein to the 'accompanying drawings.

In the process of plating-small metallic ar-I ticles with copper, nickle, silver or other metals, a quantity of such articles are usually strung on holding wires by which they may be'readily handled in dippingthem'in'to the various baths of acid, water and platingv solutions, as also by which quantities of" these small articles maybe suspended, in the metallic solutions, from suitable cross-bars or supports over; the tanks-or vats, during the plating operations; and to hold such small articles separated from eachother, so that the cleansing and platin operations may be as heretofore usually been customary to employ small metal lic sleeves which are strung on the'wires between the-articles to be plated. Theseme-1- tallic sleeves, however, hold, by

I capillary attraction, more or less of the li ui in which the articles are dipped in the p ating opera:

tions, and also present a considerable amount solution s unnecessarily wasted by being deposited on the considerable extent of surface which these sleeves or ferrules present. It

has been attempted to lessen or avoid these objections by employing small spiral coils of wire, instead of the ferrules or sleeves re 'ferred to, such coils of wire being dpe'n so as.

.to'hold less of the liquid of the baths or solutions by capillary attraction, such open coils or wire also presenting lesser amount of surfaces-on which the plating solutions become deposited. Such open, coils of wire, how

ever, soon become 'closed'by deposit thereon of the metal of the platin solution; such deposits thickening the coi s and aftera time practically closing theni up so that they berules for which they are substituted.

the objections above mentioned [bythe use 0f separating bars or links, "rules or coils of Wire-referie \separating bars ordinks' 'a're'of suchform as tions by capillary attraction;- andwthey are also, prefera very small points of contact a' ainst t earticles being lplated andwhich t ey hold separated from each other'on-t'he wires on which such articles are strong. To this'endeach of plated on the Wire on which they are strung; the bar or section of wire forming thebody'of end with eyesbymeans of which the sepa:

holding wire between the articles to be sepaof the separating bar or link, are preferably. so, bent as to form only small points of contact with the articles being plated and which are strung on the .holdingwires. 1

This invention hasfor its'object'to ayoid,

the improved .s e arating bars orjlinks comprises a piece o wire of a length-approxi mately equal to the distance apart'at-which'" it may be desired to hold two articles to be the separator being provided at its opposite r 86 rated, and which eyes are disposed at right angles to-the bed of the separatonor apjproximately so: he eyes at the oppositeends of the section forming the body portion In the accompanying drawings Figure I is l V respectively, illustrating .still -another an preferred form of the invention} proved separators consists preferably of a single piece of wire having a bodyportion a at which itmay be desired to hold the'arti- Referring to the 'drawingaeacli of theim cles to beplated' on-the holdin -wire onwhich they are strung, the. said he yportion' approximating in lengththe distance'apart having at its opposite ends eyes I) through which the holding wire referred to passes when the articles to be plated, and the links or bars separating the same, are strung on such holding wire. These eyes I) are preferably bent, or made irregular, as shown in Figs. 1, 2, 7 and 8, to form only small contact faces or points of contact, 0, with the articles to'be plated and against which the said eyes will abut; or they may be bent as shown in Figs. 3 and 4, in which case they will present the points of contact (1 for the abutting articles; or, instead of bending these eyes, as

' plated from becoming displaced shown in the other views, they may be made plain as shown in Figs. 5 and 6.,

To prevent the articles which are being from their separated, positions, so that they might get into contact with each other in the plating be deposited, so that there will be but little waste of the plating metal; and it will also be understood that these separating devices are of such construction that but little of the liquid of the different baths, into which the articles being plated are successively or alternately dip ed, will adhere to such separators; and there ore the wastage of the liquid of the baths, or mjury due to mixing the liquids of the different baths, will thus be reduced to a minimum.

Having thus described my invention .l claim and desire to secure by Letters Patent:

1. A separating device, for use in metal plating, consisting of a piece of wire having a longitudinal body portion provided at its opposite ends with eyes which are disposed sub stantially at right angles to the said body portion.

2-. A separating device, for use in metal plating, consisting of a piece of wire having a longitudinal body portion provided at. its opposite ends with eyes which are disposed sub stantially at right angles to the said body portion, said eyes being bent to present irregularities in their outer or contact surfaces, for the purpose of reducing the extent of such contact surfaces.

3. A separating device, for use in metal plating, consisting of a single piece of wire and comprising two longitudinal bars and two eyes disposed approximately at right angles to said bars at the ends thereof.

4. A shparatingdevice, for use in metal plating, consisting of a single piece of wirev and comprising two longitudinal bars and two eyes disposed approximately at right angles to said bars at the ends thereof, said eyes being bent to present irregularitie s'in their outer surfaces, for the purpose of reducing the extent of their contact faces.

In testimony whereof I aiiix my signature, in presence of two witnesses.
